Accepting Changes

Proposed changes can be resolved in three ways:
Using the Accept or Reject dialog box (most options)
Using the Reviewing Toolbar (fewer options)
Right clicking on a change and using context shortcut menu

The menu you see when you right click depends on its context so it is sometimes safer just to use the menu bar or ribbon.

Using Accept or Reject Dialog Box

you can easily move through the document resolving one at a time
best to start at the beginning of the document
Navigate using the backward and forward buttons

This gives you slightly more control than using the toolbar as it allows you to control how the document is displayed while you are making changes eg ??

You can always undo a change that was accepted or rejected infact the Accept and Reject dialog has its own Undo button.
